Mounted Bearing Diamond Seat Outer Spherical Ball Bearing Casting Type Economical

Frequently Asked Questions about the Product


1. Can the external dimensions of a cast housing be used as positioning references?

No. The dimensional tolerance of cast housings is CT9, which is relatively large and unsuitable for precise positioning.



2. What is the difference between transition fit and clearance fit?

Transition Fit: The bearing core and housing form a tight fit. Adjusting alignment requires applying torque through the shaft.

Clearance Fit: The bearing core and housing form a loose fit.



3. What precautions should be taken during bearing housing installation?

The correct installation sequence for housed bearings is: first install the housing, then the shaft. While bearing housings can theoretically be installed anywhere, ensure the mounting surface is flat and rigid to maximize bearing lifespan.
